Dual Wireless Audio Data Correction via State Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual wireless Bluetooth communication systems, the frequent switching of states between receiving and sending modes in Bluetooth devices leads to time and bandwidth wastage during error correction and data forwarding, reducing the efficiency of data transmission.
Innovation Solution
A method where the first wireless device maintains a receiving state to sequentially receive audio data packets from a wireless audio source device and forwards unmonitored packets to the second wireless device, minimizing state switching and optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error correction and data forwarding are performed by switching between receiving and sending states, then data transmission reliability is improved, but time and bandwidth are wasted due to frequent state switching
Solution Approach 1:
The first wireless device preliminarily receives all audio data packets from the audio source device before performing error correction or data forwarding operations. This preliminary reception maintains the device in a receiving state, avoiding multiple state switches, and enables subsequent error correction operations to be performed efficiently without time loss from state transitions
Solution Approach 2:
The first wireless device maintains continuous receiving action by staying in the receiving state throughout the audio data transmission process. This continuity eliminates interruptions caused by state switching, ensuring that the useful action of receiving and processing audio data continues without breakdowns or delays
2Measurement precision
If error correction packets are sent and received multiple times for each audio data packet, then data accuracy is improved, but bandwidth is wasted due to repeated transmissions
Solution Approach 1:
The patent merges multiple error correction operations into a single unified process. Instead of sending and receiving error correction packets separately for each audio data packet, the first wireless device receives all audio data packets first, then performs error correction in one consolidated operation, significantly reducing bandwidth consumption while maintaining data accuracy
Solution Approach 2:
The first wireless device performs preliminary reception of all audio data packets before executing error correction. This preliminary action allows the device to accumulate all necessary data in one receiving phase, then perform error correction efficiently without needing to switch states or retransmit packets multiple times, thereby conserving bandwidth
